Description

A kind of consumption method for supervising and system that supports current detection functionality

Technical field

The present invention relates to the strategy and the charging control technology field of mobile communication, relate in particular to consumption method for supervising and the system of a kind of support current detection functionality (TDF, Traffic Detection Function).

Background technology

Since third generation partner program stage 7 (3GPP Release7) standards system, strategy and billing function are realized by the strategy and control (PCC, the Policy and Charging Control) framework that charges.The PCC framework is a functional framework that can be applied to multiple access technology; For example; The PCC framework can be applied to UMTS (UMTS; Universal Mobile Telecommunications System) terrestrial radio Access Network (UTRAN; UMTS Terrestrial Radio Access Network), global system for mobile communications (GSM, Global system for Mobile Communication)/GSM data strengthen the grouping system (EPS, Evolved Packet S ystem) of evolution (EDGE) wireless access network, intercommunicated wireless local area network (I-WLAN) and evolution etc.

PCC has mainly realized the policy control and the two big functions of chargeing.Fig. 1 is the non-roaming composition configuration diagram of the PCC of existing Rel-11, below each logical functional entity and interface function thereof in the PCC framework shown in Figure 1 is described.As shown in Figure 1:

Business function entity (AF) is used to provide the access point of service application, and the employed Internet resources of these service application need carry out dynamic policy control.When service surface was carried out parameter negotiation, AF passed to policy control and charging regulation function entity (PCRF, Policy and Charging RulesFunction) with related service information.If these business information and PCRF's is tactful consistent, then PCRF accepts and should consult; Otherwise the PCRF refusal should be consulted, and when feedback, provided the acceptable service parameter of PCRF.Subsequently, AF can return to subscriber equipment (UE, User Equipment) with these parameters.Wherein, the interface between AF and the PCRF is a Rx interface.

PCRF is the core of PCC, is used for being responsible for the formulation of strategic decision-making and charging regulation.PCRF provides based on the network control of business data flow rule, and these network controls comprise the detection, gate (Gating Control), service quality (QoS, Quality of Service) control of business data flow and based on the charging regulation of data flow etc.PCRF sends to strategy and charging execution function entity (PCEF, Policy and Control Enforcement Function) execution with the strategy and the charging regulation of its formulation; Simultaneously, PCRF need guarantee that also these rules are consistent with user's CAMEL-Subscription-Information.Wherein, PCRF generates strategy and comprises with the foundation of charging regulation: the information relevant that obtains from AF with business, obtain from user-subscribed database (SPR, Subscription Profile Repository) with policy control with charge relevant user policy, billing control and subscription information and through the Gx interface from the PCEF acquisition and the information carrying network of relation.

PCEF be usually located at gateway (GW, Gate-Way) in, carry out strategy and the charging regulation that PCRF formulated at loading end.PCEF detects business data flow according to the business datum flow filter in the rule that PCRF sent, and then these business data flows are carried out strategy and the charging regulation that PCRF formulated; When carrying was set up, PCEF carried out resource allocation according to the rule that PCRF sends, and carried out gate control according to the information that AF provides; Simultaneously, PCEF triggers according to the PCRF events subscribed and reports event on the bearer network; According to the charging regulation that PCRF sends, PCEF carries out corresponding business data flow billing operation, and chargeing both can be online charging, also can be offline charging.If online charging, then PCEF needs and Online Charging System (OCS, Online Charging System) carry out credit management together; During offline charging, the charge information of exchange correlation between PCEF and the off-line accounting system (OFCS, Offline Charging System).Wherein, the interface between PCEF and the PCRF is the Gx interface, and the interface between PCEF and the OCS is the Gy interface, and the interface between PCEF and the OFCS is the Gz interface.Also can strengthen the PCEF function and realize current detection functionality, PCEF and TDF are integrated.PCEF can be according to this locality disposes or the PCC rule that comprises applying detection control strategy (ADC, Application Detection andControl) that PCRF issues is carried out applying detection and carry out strategy execution (like gate, redirected and bandwidth constraints).PCEF generally is positioned on the gateway of network; Grouped data network gateway (PDN-GW), GPRS (GPRS like EPS; General Packet Radio Service) GGSN (GGSN) in and interconnected wireless network local area network (LAN) (I-WLAN; Interworking WLAN) packet data gateway in (PDG, Packet Data Gateway) etc.

TDF also can independently dispose, and this moment, TDF and PCRF were through the Sd interface, and TDF can carry out applying detection and strategy execution according to applying detection control law pre-configured or that PCRF issues.PCRF is that independent TDF provides the applying detection control law, and the policy control executable operations of independent TDF function comprises gate, is redirected and bandwidth constraints.TDF does the reporting of dependent event and information (beginning from detected business/stream to PCRF and the termination of for example reporting) of business to be detected/stream to PCRF; And send the business datum stream description to PCRF, the business that is used to flow detection from PCRF of sending detects and the signaling of policing rule.There are two kinds of patterns of requested service report and active business report in TDF: requested service report manner, PCRF will notify which service needed of TDF to detect and report to PCRF; Active business report mode, pre-configured which service needed detects and report in TDF, and this mode supposes that the user agrees need not ask also can carry out.

Bearing binding and event reporting function entity (BBERF, Bearer Binding and Event ReportingFunction) are usually located in the Access Network gateway (Access Network Gateway).During like employing proxy mobile internet protocol version 6 (PMIPv6, Proxy Mobile Internet Protocol version 6) agreement between subscriber equipment is through E-UTRAN access EPS, gateway S-GW and P-GW, just there is BBERF among the S-GW.When subscriber equipment inserted through the trusted non-3 GPP access network, also there was BBERF in the trusted non-3 GPP access network Central Shanxi Plain.

SPR stores and the policy control and the relevant user policy, billing control and subscription information that charges.Interface between SPR and the PCRF is the Sp interface.

OCS and PCEF accomplish the control and the management of user credit under the online charging mode jointly.

OFCS and PCEF accomplish the billing operation under the offline charging mode jointly.

Above PCC framework has been realized UE is packet data network (PDN of visit through each functional entity; The policy and charging control of the IP connection access network of Packet Data Network) being set up (IP-CAN, IP ConnectivityAccess Network) session.

In the prior art, PCC supports dynamic consumption Monitoring and Controlling, to realize using total amount to carry out dynamic strategic decision-making based on real-time Internet resources.The consumption monitoring can be applicable to all Business Streams of single business data flow, one group of business data flow or an IP-CAN session.At present, consumption (usage) refers to user plane data traffic.In the prior art; Adopt monitoring key (Monitoring Key) to identify an instance that needs the consumption monitoring; Such as: when PCRF is that an IP-CAN session has distributed Monitoring Key and corresponding threshold value; PCEF is accumulated to the consumption of all business data flows of this IP-CAN session in the corresponding consumption of this MonitoringKey; When arriving threshold value, during the IP-CAN session termination or in the PCRF request, give the correct time, PCEF reports consumption and identifies the consumption that reports with this Monitoring Key to PCRF.When PCRF Monitoring Key that has been a Business Stream or one group of business datum flow distribution and corresponding threshold value, PCRF is carried at Monitoring Key in the corresponding PCC rule of this business data flow or one group of business data flow.After PCEF installs the PCC rule; The consumption of the business data flow that will mate with the business datum flow template (Service DataFlow Template) in the PCC rule is accumulated in the corresponding consumption of Monitoring Key; Give the correct time when arriving threshold value or when comprising last PCC rule deexcitation of same Monitoring Key or during the IP-CAN session termination or in the PCRF request; PCEF reports consumption to PCRF, and identifies the consumption that reports with this Monitoring Key.Wherein, said business datum flow template is also referred to as business datum stream description (Service data flow description), below does not give unnecessary details.

Simultaneously, in SPR, can also preserve total safe level of certain PDN of user, promptly be directed against total safe level of all Business Streams of an IP-CAN session, also can be called total safe level of the every user of every PDN.Can also preserve some concrete professional total safe level of certain PDN of user among the SPR, promptly, also can identify usually with Monitoring Key to total safe level of a business data flow or one group of business data flow.

Be established to the IP-CAN session of certain PDN as the user after, SPR is handed down to PCRF with total safe level.When PCRF carried out the consumption Monitoring and Controlling, PCRF subscribed to consumption to PCEF and reports (Usage_Report) event trigger.When Monitoring Key be included in issue in the PCC rule after, the PCC rule with identical MonitoringKey is shared this Monitoring Key corresponding threshold.When Monitoring Key was not included in any PCC rule, all business data flows of IP-CAN session were shared this Monitoring Key corresponding threshold.PCEF monitors that consumption has reached threshold value, IP-CAN session termination, all PCC rules of comprising certain Monitoring Key are all given the correct time on deletion or the PCRF explicit request consumption, and PCEF will consume situation to the consumption of PCRF report relevant Monitoring Key since the last time reports.After PCRF receives that consumption from PCEF reports, PCRF will deduct the volume value that reports from total safe level.If PCEF reports the consumption of certain Monitoring Key and need proceed monitoring, so, PCRF will provide new threshold value to PCEF; If need not to proceed monitoring, PCRF does not provide new threshold value to PCEF.When last IP-CAN session termination of user's a APN, PCRF will preserve remaining total safe level in SPR, comprise total safe level of this PDN or some concrete professional total safe level of this PDN.

Can see from existing consumption Monitoring and Controlling scheme; When existing consumption Monitoring and Controlling during to one or one group of business data flow; PCRF need comprise MonitoringKey in the corresponding PCC rule of business data flow, comprise this business data flow corresponding service data flow template in the PCC rule this moment.After PCEF installs the PCC rule, will be accumulated in the corresponding consumption of Monitoring Key with the consumption of the business data flow of business data flow template matches in the PCC rule.Thereby realize the consumption Monitoring and Controlling.When a plurality of PCC rule is shared a Monitoring Key, all can be accumulated in the corresponding consumption of this Monitoring Key with the consumption of the business data flow of the business data flow template matches of these a plurality of PCC rules.

Yet, be not under any circumstance, PCRF can both obtain the business datum flow template.When PCEF integrated during the TDF function, TDF can report PCRF to detected application (Application ID sign is adopted in this application), but PCEF at any time can both report this application corresponding service data flow template.

When TDF independently disposed, TDF also possibly can't report detected application corresponding service data flow template, and this moment, PCRF just can't issue the PCC rule that comprises the business datum flow template to PCEF, thereby can't realize the consumption Monitoring and Controlling to this application.

When existing consumption Monitoring and Controlling is directed against entire I P-CAN session; If disposed independently TDF again; Because possibly exist TDF can't detect and report the application or the data flow of stream information in the IP-CAN session, measurement and local policy that TDF can combine PCRF to provide are carried out corresponding gate or bandwidth constraints (promptly when bandwidth surpasses restriction, carrying out packet loss) to such application or data flow; For such data flow; The monitoring of the consumption of the IP-CAN rank (level) of PCEF has been made the consumption statistics in handling, but actually behind the TDF that flows through, is blocked or is redirected, and this part should not count actual amount.This can cause the consumption and final use inconsistent of user of PCEF accumulative total.

Therefore, in sum,, strengthen TDF or independent TDF framework, when PCRF can't obtain the business datum flow template, can't carry out the consumption Monitoring and Controlling of such business data flow level for PCEF based on prior art.For independent TDF framework, when carrying out other consumption monitoring function of IP-CAN level, there are the consumption and the inconsistent problem of actual amount that report, can't carry out other consumption monitoring function of IP-CAN level exactly.It is thus clear that: how to realize that PCRF can't obtain other consumption Monitoring and Controlling of such business data flow level of business datum flow template, and the detection of the IP-CAN rank consumption under TDF framework control, become the problem that presses for solution in the present consumption monitoring technique.

Summary of the invention

In view of this; Main purpose of the present invention is to provide consumption method for supervising and the system of a kind of TDF of support; Can realize that PCRF can't obtain other consumption Monitoring and Controlling of such business data flow level of business datum flow template, and the IP-CAN rank consumption under the TDF framework detects control.

Embodiment

The consumption method for supervising of support current detection functionality of the present invention comprises two sets of plan.Below set forth respectively.

One, first sets of plan is based on the consumption Monitoring and Controlling of application, can solve when PCRF can't obtain business datum flow template (being that Business Stream is described), still can carry out the consumption Monitoring and Controlling of such business data flow level.This method mainly comprises following content:

PCRF issues the consumption Monitoring and Controlling strategy of using correspondence to applying detection and controlled entity; Applying detection and controlled entity are according to this consumption Monitoring and Controlling strategy execution consumption monitoring.

Further, applying detection and controlled entity are PCEF or TDF independently.The then above-mentioned consumption monitoring that issues and carry out includes three kinds of situation: 1) PCRF issues to the PCEF of integrated TDF and uses corresponding consumption monitoring strategies; The PCEF of said integrated TDF carries out the consumption monitoring according to said consumption monitoring strategies; 2) PCRF to PCEF and independently TDF issue respectively and use corresponding consumption monitoring strategies; Said PCEF and independently TDF carry out the consumption monitoring according to said consumption monitoring strategies; 3) PCRF issues to TDF independently and uses corresponding consumption monitoring strategies; Said independently TDF carries out the consumption monitoring according to said consumption monitoring strategies.

Further, this consumption Monitoring and Controlling strategy comprises: monitoring key (Monitoring Key) is set; Application identities (Application ID) is set; Be provided for triggering the event trigger of Monitoring Key or Application ID; And consumption threshold values (Usage Threshold) is set.Wherein, the value of this event trigger can report (Usage_Report) for consumption; This consumption threshold value (Usage Threshold) can be abbreviated as UT, UT＜=TAU, and TAU is for using writing a Chinese character in simplified form of relevant total safe level (Totally Allowed Usage).

Second sets of plan is the IP-CAN level consumption monitoring function that solves under the TDF framework; Comprise the scheme of following method one and the scheme of method two; The two is that independently the TDF framework is carried out down IP-CAN level consumption monitoring scene different solutions down, below elaboration respectively.

Method one: when independently the TDF framework is carried out the monitoring of IP-CAN rank consumption down; On PCEF, carry out the monitoring of IP-CAN level consumption; The last statistics of TDF abandons consumption and reports PCRF, to be used to revise the consumption error of PCEF report, to realize IP-CAN level consumption monitoring function.This method mainly comprises following content:

When PCEF carried out IP-CAN rank consumption monitoring function, TDF added up the consumption that abandons of this IP-CAN session, and the consumption of adding up that abandons is reported PCRF, and PCRF is according to the error that consumption correction PCEF reports consumption that abandons of this statistics.

Further, this type that abandons consumption comprises: time and/or flow and/or incident; The corresponding consumption that triggers reports the type of threshold values to comprise: the threshold values that reports that reports threshold values and/or incident that reports threshold values and/or flow of time.This abandons consumption: the consumption that when TDF carries out the Flow Control function of IP-CAN session, abandons, but the consumption that the IP-CAN level consumption monitoring function of PCEF had been added up.PCEF can carry out IP-CAN level consumption measuring ability by prior art in this method.

Comprise the opportunity that consumption reports PCRF that abandons of further, triggering that TDF will add up: 1, in the IP-CAN conversation procedure, when consumption reported threshold values (like the threshold value that reports of time or flow) to arrive, TDF reported this to abandon consumption to PCRF; 2, in the IP-CAN conversation procedure; PCRF finds that the consumption of the consumption monitoring of this UE reports threshold values arrival and exists the consumption of IP-CAN level to monitor; Perhaps the consumption monitoring function of this IP-CANlevel stops; Then PCRF sends to obtain to TDF and abandons consumption and report indication, and TDF then reports the consumption that abandons of statistics to PCRF; 3, when the IP-CAN conversation end, TDF reports the consumption that abandons of statistics to PCRF.

Further, TDF reports when abandoning consumption, pairing consumption report threshold values (as the time report threshold value and/flow report threshold value and/incident report threshold value) pre-configured or PCRF is handed down to the threshold value of TDF for TDF.Exist simultaneously if threshold values that TDF is pre-configured and PCRF are handed down to these two threshold values of threshold value of TDF, then press the carrier policy execution priority and handle; If the relevant preference strategy of operator, then the threshold value that issues of PCRF has precedence over the pre-configured threshold value of TDF.

Further; PCRF receives that TDF reports abandon consumption after, can be according to carrier policy, whether decision-making (for example need continue to carry out the subsequent dose monitoring; The consumption threshold value exhausts; Then if PCRF need continue to carry out monitoring function, and TDF report to abandon consumption enough, then can continue to issue to carry out the consumption monitoring function).

Method two: when independently the TDF framework is carried out the monitoring of IP-CAN rank consumption down; On PCEF, do not carry out the consumption monitoring of IP-CAN level; PCRF issues the monitoring strategies of IP-CAN level and gives TDF; TDF carries out and reports the consumption of this IP-CAN session to give PCRF, to realize IP-CAN level consumption monitoring function.

Here it is to be noted: 1) this paper " detection " and " monitoring " that relate to is not same notion though in the consumption monitoring function of this paper is described, occur." detection " corresponding usefulness has the applying detection function like TDF, belongs to the term of discerning category and describes; And " monitoring " is consumption monitoring (usage monitoring) function of relatively all application or other consumption of IP-CAN level, belongs to statistics and reports the term of category to describe.2) this paper " the consumption threshold values " that relate to and " consumption reports threshold values " neither same notions, and " consumption threshold values " is meant the spendable consumption of this application in the consumption monitoring; And " consumption reports threshold values " is meant the trigger value that statistics need report when abandoning flow.

Below to the present invention's elaboration of giving an example.

Embodiment one: TDF function that PCEF is integrated, and TDF adopts request to report pattern.

Fig. 2 is the flow chart of the consumption method for supervising of the embodiment of the invention one, and is as shown in Figure 2, and this flow process may further comprise the steps:

Step 201 is set up in the process of IP-CAN session in the UE request, and the gateway that PCEF is positioned at receives the IP-CAN session and sets up request message, and sets up the PDN sign of carrying the ID and the PDN network of request access in the request message in this IP-CAN session.

Step 202, PCEF sends the IP-CAN session to PCRF and sets up Indication message, and sets up in this IP-CAN session and to carry ID, PDN sign in the Indication message and to be UE IP address allocated (IPAddress).

Step 203, PCRF judges also not this user's CAMEL-Subscription-Information according to ID, PCRF sends signatory document request to SPR, and in this signatory document request, carries ID and PDN sign.

Step 204, SPR returns user signing contract information (promptly signatory document is replied) according to ID and PDN sign.Comprise the customer documentation configuration in the user signing contract information, indication activates applying detection and control.In addition, also possibly comprise in the user signing contract information and use relevant total safe level (TAU, Totally AllowedUsage), total safe level of each application that needs the consumption monitoring that the expression user contracts.

Step 205, the access information of the user signing contract information that the PCRF basis is returned, network strategy, UE etc. is generated strategy.

This step is generated strategy and is comprised formulation PCC rule and event trigger.Owing to comprise the customer documentation configuration in the user signing contract information, so need the applying detection control strategy in the PCC rule.Wherein applying detection control comprises application identities (Application ID) is set, and here, Application ID representes the application that PCEF need detect.Event trigger is set, and value is that applying detection begins (Start of application trafficdetection) and applying detection finishes (Stop of application traffic detection).And the corresponding implementation strategy of the application of each possible detection, comprise gate, maximum bandwidth and redirected strategy etc.

Step 206, PCRF sends the IP-CAN session to PCEF and sets up acknowledge message, carries PCC rule and event trigger.Wherein carry Application ID and possible implementation strategy in the PCC rule.The event trigger value comprises Start of application traffic detection and Stop of applicationtraffic detection at least.

Step 207, the PCEF mounting strategy comprises applying detection strategy and event trigger.The gateway that PCEF is positioned at returns IP-CAN session foundation and replys, and in IP-CAN session foundation is replied, carries IPAddress.

Step 208, the PCEF implementation strategy comprises and carries out the applying detection strategy, to the corresponding applying detection of Application ID that comprises in the PCC rule.

Step 209, PCEF detects the corresponding application of Application ID.PCEF sends the indication of IP-CAN session modification to PCRF, carries detected Application ID and event trigger, value Startof application traffic detection.

Step 210, PCRF carries out strategic decision-making, upgrades the PCC rule.Comprise according to Application ID adjustment QoS and charging policy etc.If PCRF has obtained the total safe level TAU or the PCRF of this application and disposed the total safe level (TAU, Totally Allowed Usage) to this application in step S204, then PCRF uses to this and formulates the consumption monitoring policy.Comprising that wherein the consumption monitoring policy comprises is provided with Monitoring Key; Event trigger is set, and value is Usage_Report and consumption threshold value (UT, Usage Threshold) is set.UT＜=TAU wherein.

Step 211, PCRF returns IP-CAN session modification acknowledge message to PCEF, carries the PCC rule and the Monitoring Key corresponding threshold UT of renewal in the message.Wherein carry the corresponding Monitoring Key of Application ID in the PCC rule.

According to the signatory or PCRF configured strategy of SPR, a plurality of Application ID can share a Monitoring Key, i.e. the consumption of a plurality of application is accumulated in the corresponding consumption of a Monitoring Key.

Step 212, the PCEF implementation strategy comprises consumption Monitoring and Controlling strategy, Installation Events trigger Usage_Report.The consumption of the application that PCEF is corresponding to Monitoring Key (with Application ID sign) carries out the consumption monitoring.

In other embodiments, in step 206, PCRF just comprises MonitoringKey in the PCC rule, and issues Monitoring Key corresponding threshold UT simultaneously.PCEF, just detects strategy according to the consumption that issues in the step 206 and carries out the consumption monitoring after the corresponding application of Application ID according to the ADC rule detection, then just need not issue the consumption monitoring policy in the step 211.

Embodiment two: TDF independently disposes, and TDF adopts request to report pattern.

Fig. 3 is the flow chart of the consumption method for supervising of the embodiment of the invention two, and is as shown in Figure 3, and this flow process may further comprise the steps:

Step 301 is set up in the process of IP-CAN session in the UE request, and the gateway that PCEF is positioned at receives the IP-CAN session and sets up request message, and sets up the PDN sign of carrying the ID and the PDN network of request access in the request message in this IP-CAN session.

Above-mentioned each embodiment is to first sets of plan of the present invention, and following examples are to second sets of plan of the present invention.

In second sets of plan; For method two " when independently the TDF framework is carried out the monitoring of IP-CAN rank consumption down; PCEF does not monitor IP-CAN rank consumption, and TDF monitors IP-CAN rank consumption and reports consumption to give PCRF ", then on independent TDF, realize the consumption monitoring of IP-CAN level; The flow process that is applicable to the foregoing description two and embodiment four is described and function, is not repeated in this description here.The monitoring that is different from concrete application is handled, and for the consumption monitoring of IP-CAN level, PCRF is handed down to the monitoring key of the corresponding IP-CAN level of TDF.

Embodiment five:

What the embodiment of the invention was described is that the user sets up in the IP-CAN conversation procedure, and PCRF issues the consumption threshold value and gives PCEF, and when having the consumption monitoring of IP-CAN level, TDF adds up and reports and abandons consumption, carries out the flow process of consumption monitoring.Be that with the difference of prior art flow process PCRF need issue and abandon consumption monitoring indication to TDF, the TDF execution abandons the monitoring of consumption and reports.As shown in Figure 6, mainly may further comprise the steps:

Step 601 is set up in the process of IP-CAN session in the UE request, and the gateway that PCEF is positioned at receives the IP-CAN session and sets up request message, and sets up the PDN sign of carrying the ID and the PDN network of request access in the request message in this IP-CAN session.

Step 602, PCEF sends the IP-CAN session to PCRF and sets up Indication message, and sets up in this IP-CAN session and to carry ID, PDN sign in the Indication message and to be UE IP address allocated (IPAddress).If TDF reports pattern for request, then give PCRF with the IPAddress that goes up TDF.

Step 603, PCRF judges also not this user's CAMEL-Subscription-Information according to ID, PCRF sends signatory document request to SPR, and in this signatory document request, carries ID and PDN sign.

Step 604, SPR returns user's CAMEL-Subscription-Information according to ID and PDN sign.The safe level threshold value (TAU, Totally Allowed Usage) that comprises this user, total safe level of each application that needs the consumption monitoring that the expression user contracts sends to PCRF.If TDF reports mode for request, then SPR carries the customer documentation configuration in response, indicates whether that this IP-CAN session can carry out the ADC function.

Step 605, the access information of the user signing contract information that the PCRF basis is returned, network strategy, UE etc. is generated strategy.Comprise and formulate PCC rule and event trigger.If comprise the customer documentation configuration in the user signing contract information, then PCRF also need formulate the ADC rule.

Step 606, PCRF sends the request of TDF conversation establishing and gives TDF, provides the ADC rule request to create the TDF session.If the consumption monitoring function of IP-CAN level has been carried out in this IP-CAN session, TDF is given in the consumption monitoring indication that abandons that then issues IP-CAN level simultaneously.Alternatively, PCRF carries the threshold value that reports that abandons consumption and gives TDF (for example time or flow report threshold value).

Step 607, TDF returns the conversation establishing response message and gives PCRF, carries out the consumption monitoring that abandons data; If PCRF provides ADC rule, then ADC rule and event trigger are installed or activated to implementation strategy.

Step 608, PCRF sends the IP-CAN session to PCEF and sets up acknowledge message, carries PCC rule and event trigger.Carry the consumption threshold value of this IP-CAN session, PCEF begins to carry out the consumption monitoring.

Step 609, the PCC rule is installed or activated to the PCEF implementation strategy, carries out the consumption monitoring.The gateway that PCEF is positioned at returns IP-CAN session foundation and replys, and in IP-CAN session foundation is replied, carries IPAddress.

Through after the above-mentioned flow process, PCEF and TDF carry out the consumption monitoring according to the IP-CAN session that the consumption monitoring policy that PCRF issues is set up UE.

In the IP-CAN conversation procedure, after being triggered, TDF can report the traffic statistics that abandon of this IP-CAN level to give PCRF.At least comprise following several kinds of application scenarioss (perhaps also can be called and trigger the opportunity that flow reports that abandons):

Application example one: in the conversation procedure, TDF reports this to abandon consumption and gives PCRF when time or flow threshold arrival.

When the threshold value that reports of the consumption (time, or flow, or incident) of TDF arrives, TDF can send a request message to PCRF, and this IP-CANlevel of statistics abandons consumption after the report last report.As shown in Figure 7, this instance mainly may further comprise the steps:

Step 701, TDF detect this IP-CAN level abandon that consumption reached time or flow or incident report threshold value (TDF is pre-configured or PCRF issues report threshold value), trigger the report flow that abandons consumption.

Step 702, TDF sends a request message to PCRF, reports that this IP-CAN level abandons consumption after last report.

Step 703, PCRF abandons consumption according to what TDF reported, revises relevant PCC and/orADC rule, sends response message and gives TDF, carries amended ADC rule if having to upgrade then in the response message.If the PCC Policy Updates are arranged, then PCRF will initiate follow-up IP-CAN session modification flow process by prior art

Step 704; If the monitoring of the consumption of this IP-CAN level continues; The time that then TDF can be pre-configured according to self or PCRF issues in response message with or flow with or event threshold, repeating step 701-703 continues to carry out the consumption monitoring and the report flow that abandon consumption.

Application example two: PCRF finds that the threshold value of the consumption monitoring of this UE arrives and exist the consumption monitoring of IP-CAN level; Perhaps the consumption monitoring function of this IP-CAN level stops; Then PCRF sends to obtain to TDF and abandons consumption and report indication, and TDF then reports the consumption that abandons of statistics to PCRF.

In the conversation procedure; PCRF finds that this UE exists the consumption monitoring of IP-CAN level and consumption monitoring threshold value to arrive, and perhaps the consumption monitoring function of this IP-CAN level stops, and perhaps receives external trigger UE threshold value change etc.; Then PCRF sends to obtain to TDF and abandons consumption and report indication; Trigger TDF and report the consumption that abandons of statistics to PCRF, as shown in Figure 8, may further comprise the steps:

Step 801; Have the monitoring of IP-CANlevel consumption, PCRF receives inside or external trigger (for example, this consumption monitoring and the arrival of consumption monitoring threshold value in the conversation procedure; Perhaps this consumption monitoring function stops; Or the signatory threshold value change of SPR etc.), need obtain that current TDF abandons flow so that the check and correction actual amount then can trigger the flow process of obtaining that abandons consumption.

Step 802, PCRF sends a request message to TDF, carries in the message to abandon consumption and report indication, and request TDF reports the consumption that abandons of statistics to PCRF.If the ADC rules modification is arranged, then can provide rule after the renewal in the lump to TDF.

Step 803 after TDF receives and reports indication, is returned response message and is given PCRF, carries this IP-CANlevel and after last report, abandons consumption.

Step 804, the consumption amount that abandons that PCRF reports according to TDF is revised actual amount, revises dependency rule.If the PCC Policy Updates are arranged, then PCRF can initiate follow-up IP-CAN session/TDF session modification flow process by prior art.

Step 805; If the monitoring of the consumption of this IP-CAN level continues; The time that then TDF can be pre-configured according to self or PCRF issues in response message with or flow with or event threshold, repeating step 701-703 or 801-804 continue to carry out the consumption monitoring and the report flow that abandon consumption.

Application example three: when the IP-CAN conversation end, TDF reports the consumption that abandons of statistics to PCRF.

Through above-mentioned flow process, can carry out TDF statistics in the conversation procedure IP-CAN level abandon reporting of consumption; Except the triggering consumption of above scene reports, during conversation end, TDF is current adding up abandon consumption and also can report PCRF, as shown in Figure 9, may further comprise the steps:

Step 901, PCEF detects the triggering IP-CAN session that need terminate, and this triggering maybe be from other network elements, UE or PCEF self (for example all deletions of PCC rule).

Step 902, PCEF sends IP-CAN session termination Indication message to PCRF, carries the consumption consumption of consumption monitoring in the message.

Step 903, PCRF sends the request of TDF session termination and gives TDF, the termination of this IP-CAN session of notice TDF.

Step 904, TDF deactivates all relevant ADC rules of this IP-CAN session, sends response message and gives PCRF.Carry the consumption of this IP-CAN level in the message and monitor the consumption that abandons after last report.

Step 905, PCRF combines the consumption that reports of PCEF and TDF, and the consumption threshold value is upgraded, and sends the signatory notification request message of cancellation to SPR, carries consumption consumption or remaining safe level in the message.

Step 906, SPR receives safe level consumption or remaining safe level, and total safe level is upgraded, and returns the signatory notice of cancellation to PCRF and replys.

Step 907, PCRF returns IP-CAN session termination acknowledge message to PCEF.
